Is my Implanon implant too close to my armpit?

I got my Implanon inserted yesterday, and I have only really had the chance to feel the location of it without anesthetic now. It feels a lot closer to my armpit than what I had seen in photos online. There is probably only a 1-1.5cm gap between one end of it and the beginning of my armpit. Is this okay? Will the implant still be effective?
